UPnP UPS service

Introduction

This code implements a SSDP server and a HTTP server, in order to notify the network that a UPS is available for monitoring. This doesn't support subscription events just yet.

First, install Python3: sudo apt-get install python3

The in the project directory run pip3 install -r requirements.txt

Verify your ups is setup:

upsc myups 2> /dev/null
battery.charge: 100
battery.runtime: 3840
battery.type: PbAC
...

Test running the service: ./__main__.py
